PR 5223B Programmable f/I-f/f Converter

Advanced features

• The 5223 transmitters can be configured with a standard PC and the Loop Link communications unit or delivered fully configured.

Application

• The f/I function performs frequency to current and voltage conversion.
• The f/f function can be used for pulse division or multiplication and as a buffer collecting fast pulse trains.
• A scale factor may be entered in all functions. Using both digital inputs, pulse addition or subtraction are possible.
• The frequency generator function is used as e.g. a time base or clock generator.
• Input and supply polarity reversal protection.
• Current and voltage output signals galvanically separated from the supply and the inputs.
• Programmable digital outputs including NPN, PNP or relay options.
• ATEX units have input for mechanical contact and NAMUR inductive proximity sensor.

Technical characteristics

• 5 front LEDs, indicating f1 and f2 active inputs (not NPN), Dig.out.1 and 2 active outputs, and a programmable error signal.
• Analog current output can be configured to any current within 0…20 mA range.
• Voltage output range is selectable between 0…10 VDC and 0…1 VDC by use of internal jumpers.
• Input range:

Frequency: 0…20,000 Hz

Sensor types: NAMUR, tacho, NPN, PNP, TTL, S0

• Output range:

Current and voltage output: 0…20 mA / 0…10 V

Relay outputs: 0…20 Hz

NPN and PNP output as f/f: 0…1000 Hz

NPN and PNP output as generator: 0…20,000 Hz
